/ car camping with a bad back

What are peoples' personal recommendations for something to sleep on when car camping (ie space and weight no issue) with a bad back? The thickest thermarest on the market? Memory foam doubled over? old fashioned camp bed? any suggestions gratefully received. my missus is very keen to join me and the boys in a tent next year!

In reply to Sam Beaton: I've had back issues and now use the thickest alpkit self-inflating mattress (was called Fat airic when I got it, think it may be called Dozer now?). Can make as hard as you like by topping up the air by blowing into valve and it keeps you insulated. Much much better than when used to share a double air bed (which went soft, was cold, could feel every movement of partner, ages to blow up etc). I'd recommend one of the self-inflating mattresses - thermarest/alpkit/whatever (love my alpkit - half the price of a thermarest)

In reply to Sam Beaton: The present Mrs deepstar was`nt at all keen on sleeping in my van until I got her a memory foam mattress now she happily snores away on her camp bed on our way down to Geneva.Now all I have to do is to get her to like skiing!

In past, have tried thickest Thermarest, campbeds, airbeds etc and, in my view, none of them work with the bad backs/camping combination. Decent memory foam however does the job. Also camping took on new meaning when car/tent was replaced by small van/tent (VW Caddy Maxi,5 seats plus bed platform) creating comfy bed 'indoors' for the adults and tent for the kids. Almost an hotel.

Yep, I've never got on with a thermarest, but find that a fleece blanket folded oved a couple of times and layed on a rollmat works really well for my back and neck. It's an awkward solution, but I can't really afford the trial and error process with more expensive mats. I have an old memory foam mattress topper on my bed at home that really helps, but it's too big and heavy for even car camping. I'd be interested if anyone has found more portable ones for camping though.

I found it's not just about managing to be comfortable when sleeping with a bad back, it was trying to get up off the floor, crawl in and out of teh tent, get dressed, put shoes on etc. This bed (and a large tent!) solved that for me. It's pretty high so makes a good bench seat as well. Obviously no good in a 2 man tent though!
